No need to worry, I am here to help! Let's break down the problem into smaller parts to make it easier to understand.
First, let's define the terms that are mentioned: center of mass, linear mass density, and total mass.
- Center of mass: This is the point at which the mass of an object is evenly distributed, meaning that if you were to balance the object on this point, it would not tip over. It can be calculated by finding the weighted average of all the individual masses in the object.
- Linear mass density: This is a measure of how much mass is present in a given length of an object. It is usually represented by the symbol lambda (λ) and is calculated by dividing the mass of the object by its length. So, in this problem, we are given the linear mass density of the rod, which is 0.300 x20.600, in kg/m.
- Total mass: This is simply the sum of all the individual masses in an object.
Now, let's apply this knowledge to the problem. We are given a rod that is 2 meters long, with one end at x=1.00 m and the other at x=3.00 m. We are also given the linear mass density of the rod, which is 0.300 x20.600, in kg/m.
To find the total mass of the rod, we need to first find the mass of each section of the rod. This can be done by multiplying the linear mass density by the length of each section. So, for the first section (from x=1.00 m to x=2.00 m), the mass would be (0.300 x20.600) x (2.00-1.00) = 0.300 x 20.600 x 1.00 = 6.18 kg. Similarly, for the second section (from x=2.00 m to x=3.00 m), the mass would be (0.300 x20.600) x (3.00-2.00) = 0.300 x 20.600 x 1.00 = 6.18 kg.
Now, to find the total mass of the rod, we simply need to add the masses of each section together. So, the total mass of the rod would be 6.18 kg + 6.18 kg = 12
